Abstract
Bridge is an important part of road construction, traffic engineering is that we have a critical hub, it plays a vital role in the transport and traffic development. Bridges also intuitive understanding of a reflected critical infrastructure of national economic and social development of a country or region's economic strength, scientific and technological progress, the development of productivity, comprehensive national strength, the paper describes a carbon fiber prepreg with foam core bridge model material production, to enable the situation in the best possible light, designed to complete the calculated load-bearing task interface as a bridge of composite materials, establish a reasonable load transfer interface model to study the interfacial shear strength and interface failure form, can provide optimized composite interface and improve the overall performance of composite theoretical design guidelines, is a carbon fiber composite material having high strength and high modulus of the composite material, its specific strength and modulus of the comprehensive index, now in the presence of a material it is the highest. In the high intensity limit field density, stiffness, strength and fatigue properties in the temperature requirements, high chemical stability conditions, carbon fiber composite materials have a strong advantage, this research design using carbon fiber composite materials, production and simulation model of the bridge, in the light of the conditions of sufficient quality, high strength can carry the load, can provide theoretical guidance for the design optimization of composite interface and improve the overall performance of the composite material.
